ABSTRACT
i3-MARKET leverages on blockchain technologies (e.g. Hyperledger and Ethereum) to build a trusted, interoperable, and decentralized substrate (backplane) allowing to create a federated data market where data spaces and marketplaces are able to trade data assets among each other. The i3- MARKET is mostly a set of independent subsystems with a self-contained functionality such as the identity and access management system, the semantic engine subsystem, data access subsystem, etc. Most of these subsystems have broken down their functionality into atomic and loosely coupled components exposing their functionality through a REST API, which yields a microservice-based nature to the i3-MARKET system
